Analysis of Dynamic Electrocardiogram Performance and Arrhythmia in Patients with Hypertension Combined with Left Ventricular Hypertrophy
Objective To explore the dynamic electrocardiogram performance and arrhythmia in patients with hypertension combined with left ventricular hypertrophy.Methods 120 patients with hypertension who were diagnosed and treated in Zhengzhou Fifteenth People's Hospital from May 2021 to October 2022 were selected.According to whether there was left ventricular hypertrophy,they were divided into the combined group(n=34)and the hypertension group(n=86).At the same time,120 healthy people who had physical examinations in our hospital were selected as the control group.All patients underwent dynamic electrocardiogram examination and heart rate and blood pressure index examination and comparison.Results The heart rate(HR),systolic blood pressure(SBP),and diastolic blood pressure(DBP)of the patients in the combined group were higher than those of the patients in the hypertension group and the healthy people in the control group.The HR of the patients in the hypertension group was lower than that of the healthy people in the control group,and the SBP and DBP were higher than those of the healthy people in the control group,with statistically significant differences(P＜0.05).The RV1+SV5 and RI+SⅢamplitudes of the patients in the combined group were lower than those in the hypertension group,and the Cornell and Sokolow-Lyons voltage indices were higher than those in the hypertension group,with statistically significant differences(P＜0.05).The detection rate of arrhythmia in the combined group was higher than that in the hypertension group,with statistically significant differences(P＜0.05).The results of the Receiver Operating Characteristic(ROC)showed that the area under the ROC curve for the diagnosis of left ventricular hypertrophy by RV1+SV5,RI+S Ⅲ amplitude,Cornell,and Sokolow-Lyons voltage was 0.700,0.784,0.769,and 0.729,respectively,with statistically significant differences(P＜0.05),and the cutoff values of each index at this time were 0.302 mV,0.444 mV,2.354,and 3.544.Conclusion Patients with hypertension combined with left ventricular hypertrophy may have more obvious abnormal blood pressure phenomena,and the detection rate of arrhythmia in patients is higher.The use of dynamic electrocardiogram to detect left ventricular hypertrophy has certain diagnostic efficacy.
